The invention relates to a main landing gear compartment ventilation device and an aircraft comprising the same. In the device, a stamping air inlet is positioned on a skin stamping side; the main air supply pipeline is communicated to the stamping air inlet; the ventilation disc is located at the tail end of the main air supply pipeline and used for conveying ram air to the position close to an airplane wheel assembly in a main landing gear cabin. The bypass pipeline is communicated to the stamping air inlet; the skin exhaust port is positioned at the tail end of the bypass pipeline; the flow self-adjusting module is installed in the bypass pipeline, the throttling shrinkage structure limits a flow channel, the air bag is located in the flow channel, and the flow area of the flow channel is changed through expansion or shrinkage of the air bag. One end of the heat pipe is connected with the air collecting cover, and the other end of the heat pipe is inserted into the air bag and used for transmitting heat of the airplane wheel assembly into the air bag so that the air bag can expand or contract. According to the technical scheme, the cooling system has the following beneficial technical effects that the flow of the main air supply pipeline can be automatically adjusted according to the temperature state of the airplane wheel assembly, and the main landing gear cabin supplies cold according to needs.

    本发明涉及主起落架舱通风装置及包括该装置的飞机。该装置中,冲压进气口位于蒙皮冲压侧;主送风管路连通至冲压进气口;通风盘位于主送风管路的末端,用于将冲压空气输送至主起落架舱内的机轮组件附近;旁通管路连通至冲压进气口;蒙皮排气口位于旁通管路的末端;流量自调节模块安装于旁通管路中,节流收缩结构限定流道,气囊位于流道内,通过气囊的膨胀或收缩,改变流道的流通面积;热管一端与集风罩相连接,另一端插入气囊中,用于将机轮组件的热量传递至气囊中,以使气囊膨胀或收缩。根据上述技术方案,本发明能起到以下有益技术效果:能根据机轮组件的温度状态,实现主送风管路流量自动调节,主起落架舱按需供冷。
